Glassco Class AS Single-Mark Volumetric Pipette — Batch Conformity Certificate
The Glassco Class AS single-mark volumetric pipette is a precision glass pipette manufactured to DIN/ISO standards, providing the highest available accuracy class for single-mark volumetric pipettes. Each pipette is supplied with a batch conformity certificate confirming compliance with Class AS accuracy tolerances — providing the documented traceability required for volumetric glassware used in validated pharmaceutical analytical methods, GLP-compliant research, and accredited testing laboratory applications.
The single calibration mark indicates the precise delivery volume, and the brown graduation markings on clear borosilicate glass provide strong visual contrast for accurate meniscus reading under standard laboratory lighting conditions. Available in capacities from 1mL to 100mL, these pipettes are supplied from Glassco’s European warehouse in the Netherlands for fast and reliable delivery across Ireland.
Key Features
Class AS Accuracy — DIN/ISO Compliant
Class AS is the highest accuracy designation for single-mark volumetric pipettes, combining the tight tolerances of Class A with rapid drainage characteristics — ensuring complete and reproducible liquid delivery within the shortest practical drainage time. Compliance with DIN/ISO standards confirms dimensional accuracy, tolerance grade, and material quality across all sizes.
Batch Conformity Certificate Supplied
Each order is supplied with a batch conformity certificate confirming compliance with Class AS accuracy requirements. This batch certification provides the documented traceability required by regulated laboratory environments — including pharmaceutical QC, GMP-compliant facilities, and accredited testing laboratories — for volumetric glassware used in validated analytical methods.
Single Calibration Mark — One Precise Volume
The single calibration mark at the defined volume ensures that each pipette delivers one specific, precisely defined volume — making these pipettes the appropriate choice for calibration standard preparation, reference standard dilution, and any analytical application where reproducible delivery of an exact volume is critical to method accuracy.
Brown Graduation Markings
Brown graduation markings on clear borosilicate glass provide strong and durable visual contrast for accurate meniscus reading — an important practical consideration in routine pipetting workflows where reading speed and accuracy must be maintained across large numbers of sample preparations.
Borosilicate Glass Construction
Manufactured from borosilicate glass, providing excellent chemical resistance to the aqueous solutions, organic solvents, acids, and bases encountered in routine volumetric pipetting applications across pharmaceutical and analytical laboratory environments.
EU Warehouse — Fast Delivery to Ireland
Supplied from Glassco’s European distribution warehouse in the Netherlands, providing fast and reliable delivery across Ireland with significantly shorter lead times than direct import from outside the EU.

Applications
- Pharmaceutical QC solution preparation — accurate single-volume delivery for the preparation of reference standards, assay solutions, and calibration samples in validated analytical methods
- Calibration standard preparation — reproducible delivery of precisely defined volumes for calibration curve preparation in analytical chemistry workflows
- GLP-compliant research — Class AS certified volumetric pipettes supporting qualification documentation requirements in regulated research environments
- Titration — accurate delivery of titrant or analyte solutions where precise and reproducible volume delivery is critical to titration accuracy
- Accredited testing laboratories — batch-certified Class AS pipettes meeting ISO documentation requirements for accredited laboratory volumetric glassware
Volumetric vs Graduated Pipettes — Which Do You Need?
Single-mark volumetric pipettes are the appropriate choice when reproducible delivery of one specific, precisely defined volume is required — such as in calibration standard preparation and validated pharmaceutical analytical methods. For applications requiring delivery of a range of different volumes from a single pipette, the Class AS Graduated Measuring Pipette Type 3 provides multi-volume delivery capability with the same Class AS accuracy designation.
